i I f; FEE -1i vnnvInor m altime,simmer g ea esx wesaizrte i '01: thisinvention is to provide for sterilizing milk bottles, in crates,withemploying a heating element of commercial type, and other elementsof special construc- I tion described below.

A further Object is to provide for 7 charging steam into the bottleswhen in inverted position, the steam on emerging cleansing the exteriorof the bottles before being condensed. r p 1 A still further object isto provide a boilerproportioned to rest on the top ofan oil,

stove of the typeused'for cooking purposes,

the boiler having an extensive heating :sur face and having a depressedtop serving as' a drip pan, and'sald vtop mounting a plurality-ofnozzles for discharging steam tothe 7 interior of theinverted: bottleswhen the crate is supported bythe'pan'.

A still fu'rtherobject. is to provide for draining off thecondensedsteam' upon the 1 completion of the operation of cleansing theexterior of the bottles. 7 r

WVith the'foregoing and other objects in view, the invention consists inthe novel construction and arrangement of elements described,illustrated and claimed, it being understood that suchmodification-.may" be 30 made as fall within the scope ofthe claimswithout departing from the spirit of the in.-

vention.

V In the drawings forming part of thisap plication, r p p Figure 1isaview in vertical section showing the crate with the bottles therein,in position for the sterilizing peration,-the

boiler mounted on the heater being broken away to show a depressedtop. aFigure. 2 shows the boiler in side elevation,

Figureft is a fragmentary section on an enlarged scale, the sectionbeing on line-H of'Figure 3. i

Figure 5 shows the boiler in end elevation, a portion being brokenawayto show a we,

ter inlet connection, the view also illustrating a drain pipe havingcommunication with the space above the depressed top. I

While various forms of heating elements may be employed, I haveillustrated more or less conventionally a commercial type of oil cookingstove, the-frame of whichineludes top 10, standards 11, 12, 'andlowerlongitudinal element 13. The :burners are des nated ii anax lead thealwa s or air pipes are. shown at 16 and 17, the latter out the use ofextensive apparatus, and by being ,in alinement with stove holes 19,20.; r The boiler 21 comprises along fiat bottom 22,.end members 23, 24,sidewalls 25, 26, and a depressed top 27 ,this1 element last namedconstituting aidrip pan, and Ibeingpperhaps one-half ofan inch, below;the upper edge of thevertical walls of the boiler; "A water inlet,connection 28, is 29 and a'drainpipe 30 for condensed steam a providedwith I a cap,

is located as shown.

. The. boiler maybe conveniently lifted. by

handlesr32 and 33, and the water level is ascertained through glass 34;

discharge nozzles 35,".extending vertically [through the depressed topof the boiler, conv'ey the steam to the interior of the inverted bottlesdesignated 36'the bottles being still a I in the crate-'37 of the, typeshown. Crates of this type are'l'open at the'top and at the bottom,andthe bottles are supp rted there i in by transverse metallic or otherretaining devicesJ v The nozzles each include a lower flanged Steam maybe raised in this boiler, and" end 38 having steam-tight connection withthe under side of the depressed top 27. One

nozzleis provided foreach bottle of a crate of unit size, the nozzlesbeing correctly spacedto conform with the spacing of the bottles. Theboiler will be made in various standard sizes, with the requirednumberof nozzles for each size of crate. The drip crate tobe handled, andprovides an exterior space 39 in communication with the drain. pipe 30;

' Thecrate having been placed in position andathe water heated to therequired de-. igree, steam passes through the nozzles into the invertedbottles, and emerges through the neckfportionsfthereof, around thenozzles, and passes thence m an upward dlI'eCtlOD costof the 'apparatusas compared: with be made of heavy galvan- 100'" around the'sides of thebottles, and water-of tion flows to the drip pan and out the. elaboratebottle cleaning devices ire quently used,are features of special importance. 1

What I claim is: a I In a device of the kind described, a boilerproportioned to support in inverted position 90 pan, or depressed top27, is larger than the i T a, crate of bottles of the type wherein thebottles are secured Within the crate with their neck portionsterminating below the edge portion, of the crate, the top of the boilerbeing depressed toform a peripheral Wall, a drain pipe extending fromthe de-' pressed stop,

a plurality of Vertica11y'dis posed nozzles mounted on the depressedportion of the top and arranged to enter the 1 V 19 bottles carried bysaid icrate for supplying V steam to the interior thereof the nozzlesbeing adapted to project into the necks of the bottles when, the crateis applied with its .7
